CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 337,850, dated March16, 1886. Application filed October 8, 1885. Serial No. 179,342. (Nomodel.)

To all whom it may concern:

Be it known that we, WILLIAM MoMULLIN and WILLIAM R. MCMULLIN, of Adel,in the county of Dallas and State of Iowa, have invented a new anduseful Improvement in the Mechanism of Corn-Planters, of which thefollowing is a specification.

The invention relates to the manner of throwing the dropping-bars ofcorn-planters by the check-row dropper, the object of the inventionbeing to do away with the complicated mechanism as now employed by allcheck-row corn-planter attachments.

The invention consists in the arrangement of the dropping-bar and themechanism connected with it,and rope or wire which throws the bar,substantially as shown in the accompanying drawings, in which similarletters of reference indicate like parts.

Figure 1 is a sectional top view in detail, Fig. 2 being a rear view,partly sectional, in which appears in detail the mechanism designed as asecond drop.

Upon the frame-work of the corn-planter rests the dropping-bar A,attached to which is the half-circle hoop E. Around E is the thumb-pieced, to which is fastened the spring D, connecting with the short standard0, which projects through a slot in the bar A. At the end of the bar Ais an irregular-shaped piece, B, which is loose on the bolt b, againstwhich and through the guide J slides the rope 1, upon which are balls iat regular in tervals.

The second drop (shown in Fig. 2, and which is operated by the bar A)consists of the piece F, which oscillates on the pin f.

The operation of the device is as follows: When the corn-planter is inmotion, the rope I slides through the guide J. The balli strikes thepiece B, which throws the bar A. After the ball t'passes the piece B,the spring D, attached to the short standard 0, which is fixed in theframe-work of the planter, pulling on the thumb-piece d, which is aroundthe hoop E, attached to the bar A, draws the bar A back to its normalposition, having made all the movements to drop one hill. As eachsuccessive ball on the rope presses on and passes the piece B, the samemovements are obtained. To drop from the other side of the planter,thecheck-ropeisadjustedtothatside. Thethumbpiece d is changed to'the otherside of the hoop E, which moves the bar A in position to be thrown asbefore. The grain dropped by the bar A is caught by the second drop,behind the projection G, when at the next throw of thebar A the seconddrop, F, working in unison with the bar A, exposes the hole H and dropsthe grain to the ground.

\Vhat we claim is- The combination of the bar A, the piece B, the guideJ, the standard 0, the spring D, with thumb-piece d, and the hoop E,arranged to be operated by the check-row wire I and the balls z,substantially as set forth.
